1. Association between stop bleeding and adverse outcome of patients from road traffic accident by first response unit and basic life support unit Prat Intarasaksit 1

2. Background 2

3. 3

4. background Emergency Medical Service (EMS) Dispatch Center Advance Life support Basic Life support First response 4 Intermediate Life support

5. Objective To determine whether type of emergency medical units and other factor are association with of stop bleeding outcome of road traffic accident patients 5 Basic Life support First response

6. Variables Independent variables EMS units (FR, BLS) Type of wound 6 Dependent Variables Stop bleeding outcome

7. Methods 7

8. Baseline characteristics of road traffic accident 8 GenderRegion FR BLS male

9. Baseline characteristics of road traffic accident 9 Wound (Abrasion ) Stop bleeding inappropriate

10. 10 Multivariable analysis

11. DISCUSSIONS Another finding in this study was that the number of male injury victims is significantly higher than their female. Because man has aggressive driving in men. 11

12. DISCUSSIONS Southern region had ratio of stop bleeding inappropriate higher than other region in both EMS units because first trauma case for BLS treatment has severer than FR units therefore it had mistake occur in BLS units than FR unit 12

13. DISCUSSIONS Second, stop bleeding inappropriate caused from lack of EMS team, result from NIEMS shown that southern region had slightest EMS team in Thailand, 55.2% EMS team coverage in southern region, but more than 60% of EMS team in each region for help patients, it’s caused to inefficient for stop bleeding or other trauma management 13

14. Strength of the study This study is the first to our knowledge to analyze data that is a nationally representative sample from the real practice. Limitation of the study Case record form in EMS doesn’t generate for research thereby that might missing some data or value and has duplicate in each variables. 14

15. Conclusion According to results both EMS units (First response unit and Basic life support unit) has each stop bleeding inappropriate, higher in FR unit Because staff in BLS units has more training hours than FR units. Therefore, should be increased another program and hours of training for improve both team for trauma management skill. 15

16. Recommendations Should determine the outcome on other trauma management in patients from other case and compare with other EMS units. 16

17. Recommendations Should assess accuracy in EMS documentary. Because EMS documentation is often performed in chaotic and complex settings: in the dark, rain, and cold, under time pressure, and sometimes under threat to personal safety that maybe error in data record 17
